I've used Hames Reid twice. The first time was 6 months ago -they cleared a block pipe due to tree roots. Back then they were prompt and communicated well and even followed up with a diagram of the backyard and where the access point to the pipes were located. We had the same issue again recur recently and due to their good service back then, I did not hesitate to call them back.
Good points this time- easy to book in, received a text message when they were on their way.
Bad points - failed to communicate with me via phone as they told my secretary they would. Also charged twice the amount as they did 6 months ago for doing exactly the same job. I sent a couple of emails asking for more information about the location of the blockage so we could mitigate this in the future but did not receive any response. Also can't fathom why they would charge twice the amount for the same job - I then saw their reviews on WOMO and noted similar issues.
First job they would have received 5 stars. This job - 1 star. Therefore their average is 3 stars.
For what it's worth, I used a different plumber for a different property for the same problem of blocked pipes from tree roots -the other company provided emailed video footage of the location of the problem and gave an upfront quote of the cost to remedy it as soon as it was diagnosed. Much more transparent billing.

Approximate cost: $600

I called Larry based on these reviews. Found him to be friendly, efficient and trustworthy. I would recommend him.

Approximate cost: $250

Several medium trees and one large tree pruned. Friendly and polite, although my advice is ensure you get every aspect quoted for. We found that there were a couple of trees we mentioned needing work done on and we were verbally told it 'wouldn't cost much', but it didn't get included on the written quote. We reminded them on the day and then were sent an invoice for a larger amount than expected. Otherwise, a good service.

Found to be professional and on time with delivery and pick ups. Pleasant receptionists. Easy ordering system. Clean cartons. A very good alternative to cardboard boxes. Highly recommended

Moved from a medium to a large house. We did our own packing and had everything labelled. Metro Movers were efficient, friendly and careful with our belongings. I would recommend them and would use them again.

CAUTION!
Installation of home alarm system. Found them to be professional and courteous and trustworthy. Cleaned up after themselves.
I initially gave this company 5 stars but have now decided to edit this after several months of attempting to address problems. After less than 12 months from installation,we developed problems with the remote controls. I contacted Chris, who stated he was aware that there were problems with the remotes with other people. Discussion was had to arrange replacement. However since this conversation it has been several months and numerous phone calls (none returned) and emails later (some returned) there still has been no resolution. Arrangements for him to come over to repair or replace them were determined via email, but he did not arrive or call to state he was not coming. The security controls remain non-functional to date.

Provided on-site quote. Turned up on time. Was very thorough and professional and seemed very knowledgeable and trustworthy. Provided a prompt quote after the site visit. I did not choose them in the end due to a more competitive quote, but would still recommend them.

Approximate cost: $18000

I received a quote from Paul who provided an on-site visit. He was on time, polite and thorough. In the end, I chose a more competitive quote, but would recommend this company based on initial dealings.

Approximate cost: $10000

We chose NSRT even though they were not the cheapest quote we received. It turned out to be one of those horror stories you hear about tradies. Numerous issues. The main and most important point was the extremely poor quality of work. They were engaged to:
-supply and install new tiles for the whole roof
-replace valley irons

The roof ended up being so poorly done that it leaked significantly more than before they touched it. We had an independent plumber assess the work and the pictures he took showed the extremely poor quality of work they did. This includes:
-trashing of the existing under-flashing, resulting in water entering the roof and causing internal damage
-disrupting the sky light as a result of the under-flashing being damaged
-sections of the roof had visible humps
-cracks were present in the capping
- tiles were jagged and not cut cleanly
Needless to say, there have been ongoing issues that still remain unresolved despite numerous calls and correspondence.

Approximate cost: $14000
